In August 2008, we've appointed your company for the transportation service of a batch of devices / parts, however, the said goods have been reported lost due to the mis-handling by your side. In this connection, please sign on this document to confirm that the responsibility should be solely undertaken by your side.

Our company had sent you a batch of spare parts in August. However, these goods were lost during delivery in an accident. We hereby request your company to confirm the same by signing the enclosed declaration that it is your sole responsibility for such loss and not our own fault
